The USG No. 1 Pottery Plaster is famous industry-wide for working reliability, productivity, and highly successful results.  Great for all types of ceramic slip casting applications, pottery plaster is formulated for long life and reduced breakage (stronger molds).


  • Economical, all-purpose pottery plaster.
  • Produces more absorbent pottery molds.
  • Specifically formulated for most slip casting applications in the ceramic industry.

Use potable water at temperatures between 70° and 100° F (21 ° and 38° C).  Since variations in slurry (the plaster and water mixture) temperature produce variations in setting time, it is important to keep both the plaster and water in a stable temperature environment prior to use.  The higher the temperature of the water, the shorter the set time.
